The present invention provides an organic light-emitting element, comprising a substrate, a first electrode, more than one organic layer film comprising a light-emitting layer, and a second electrode. The light-emitting element further comprises a cover layer. The cover layer is located on the second electrode, and comprises a high refractive layer and a low refractive layer. A material for the low refractive layer of the cover layer is a boron complex organic small molecular compound. The organic light-emitting element provided by the present invention can achieve high light-emitting efficiency and color reproducibility. The organic light-emitting element of the present invention can be used for an organic EL display, a backlight source of a liquid crystal display, illumination, a sign board, an identification lamp, etc.

Organic light-emitting element

Provided is a polysiloxane, containing at least one segment selected from molecular structures shown by formula 1 below, wherein in formula 1, Q is an alkyl containing an alcoholic hydroxyl and having less than 12 carbon atoms in the main chain, or an alkyl containing an alcoholic hydroxyl and having less than 12 non-hydrogen atoms in the main chain and containing a heteroatom; and T is a hydroxyl, an alkyl, an alkyl containing an alcoholic hydroxyl and having less than 12 carbon atoms in the main chain, or an alkyl containing an alcoholic hydroxyl and having less than 12 non-hydrogen atoms in the main chain and containing a heteroatom. A doped slurry and a mask material prepared by using the polysiloxane, on the basis of having a good diffusivity, also have a good barrier property and a small amount of diffusion in air. In addition, according to a manufacturing method for a semiconductor, the diffusion in air of a doped impurity in the doped slurry is further reduced, so that the quality of a doping process can be further improved.
